Public bug reported:

Hi,

I upgraded to focal and since then I have the following problems with my
audio on my laptop:

1. If I start my laptop with my headphones pluged-in I initially have
sound from my headphones, If I unplug my headphones speakers work
normally. But when insert my headphone again the sound stops from the
speakers but I have no sound from my headphones. To "fix" the problem I
have to go to the kde systemsettings and in "audio" settings in the
advanced tab change the profile to something else and then restore the
option.

If I start the laptop WITHOUT the headphones pluged-in then everything
works as it should. I have deleted the ~./config/pulse folder but it
changes nothing.

2. If the computer starts WITHOUT headphones and the computer goes into
hibernation when it wakes I get a static noise from the speakers
(although the headphones are plugined-in) I have to reboot the computer
in order to fix this.

Kind Regards
